The following section describes the problem you are expected to solve using MATLAB andAutodesk Robot, or other general programming language and finite element (FE) softwarepackage, and specific details of the tasks and outputs to feed in to your report. An overallsummary of the assessment criteria is provided at the end of each section. Consider the ground motion time history signal shown in Fig. 1. As earthquake loading is nota deterministic load (i.e. it cannot be described analytically) and is highly transient, a corre-sponding structural response is often calculated with the use of a response spectrum. A response spectrum is a plot of period versus acceleration, which shows the maximum re- sponse of a linear single degree of freedom (SDOF) system for a given component of an earth- quake ground motion. Using MATLAB or other general programming language you are asked to generate an elastic response spectrum based on ground motion data. Fig. 2 visually illus- trates the generation process of a response spectrum. Each point in the spectrum corresponds
A background overview of the design philosophy of response spectra, and its appropri- ateness for seismic analysis; 10 %
• A discussion of the obtained elastic response spectrum and the algorithm/method that you have implemented to obtain it, including a pseudocode/flowchart and relevant cri- teria; 15 %
• Validation of the method that you have adopted for numerical integration of the equation of motion. 15 %
2 Task 2 – Seismic design of a steel framed structure
In this task you are asked to carry out a seismic analysis and design a steel framed structure against a seismic event using Autodesk Robot software or other FE package, see Fig. 4. You have to design the structure following the guidelines prescribed in the Eurocode 8 for a nonlin- ear pushover analysis. To support the design of your steel framed structure, you are expected to produce a report (1200 words) including CAD/BIM drawings of the designed frame.
Requirements
The structure should have the following geometrical/material requirements:
• have a specific number of portals that is individual to you and is listed in column 3 of Table 1;
• have a minimum distance between portals of 2.5 m;
• have a minimum clear height of 4.2 m;
• each portal of the frame should have a clear span of 8 m;
• you have to consider the self-weight of the structure, a dead load of 4 kN/m and a live load of 1.6 kN/m on the roof beams.
• be made of steel grade S235 with a perfectly plastic material model.
